Description:
In SchemaProvider.cs, methods GetIndexes and GetIndexColumns pass their restrictions directly to GetTables. This only works if the restrictions are no more specific that schemaName and tableName. If IndexName is given, this is passed to GetTables where it is treated as TableType, so no tables are returned (unless your index name happens to be "BASE TABLE" or "VIEW"). This means that both methods return no rows.

How to repeat:
Compare above methods with method GetColumns in the same source file.

An entry was added to the 5.1.8 and 5.2.6 changelogs:

Calling GetSchema() on Indexes or IndexColumns failed where index or column names were restricted.

In SchemaProvider.cs, methods GetIndexes() and GetIndexColumns() passed their restrictions directly to GetTables(). This only worked if the restrictions were no more specific than schemaName and tableName. If IndexName was given, this was passed to GetTables() where it was treated as TableType. As a result no tables were returned, unless the index name happened to be BASE TABLE or VIEW. This meant that both methods failed to return any rows.
